Abstract: Conventional water filtration methods cannot be generalized for use in direct wastewater filtration for drip (trickle) irrigation systems. Effluents from an oxidation ponds‐reservoir system and from an activated sludge ...

Abstract: Fouling experiments of thin film composite and cellulose acetate reverse osmosis membranes by aluminum oxide colloids are reported. Membrane fouling was investigated at various solution chemistries under fixed hydrodynamic ...

Abstract: A novel optical technique is used to investigate the dynamics of coagulation of particle suspensions with aluminum salt. The relative size of aggregates formed during coagulation, expressed as a “coagulation index,” can ...

Abstract: The efficiency of arsenic removal from source waters and artificial freshwaters during coagulation with ferric chloride and alum was examined in bench-scale studies. Arsenic(V) removal by either ferric chloride or alum was ...

Abstract: Pilot-scale experiments were performed to investigate the effectiveness of enhanced coagulation in removing particles and trihalomethane (THM) precursors from two surface source waters: California State Project water and ...
